Meiji Restorations: Defining Preservation, Education, and Architecture for Modern Japan
Japan’s modern age began with the Meiji period (1868-
1912), an era of government-sponsored Westernization
in art, education, and architecture. In this climate,
government policy barely concerned itself with
traditional Japanese architecture. However, historical
buildings soon attracted attention from disparate figures,
including priests, government officials, educators,
art reformers, architects, and master builders. Some
groups drew on pre-Meiji precedents to argue for
government support, citing the historical state funding
of religious institutions. Others, such as the artist and
critic Okakura Kakuzô, used modern concepts of art
and history to argue for the relevance of historical art.
The architect Itô Chûta, learning from both Okakura
and the master builder Kigo Kiyoyoshi, used historical
Japanese architecture to place Japan in the context
of world architecture. Preservation concepts became
fundamental in the development of architecture and
the fine arts for modern Japan. Preservation matured
at the intersection of these diverse approaches and, in
turn, served as a forum for officials, critics, architects,
engineers, and builders to conceptualize architecture
for modern Japan. The 1897 Ancient Shrines and
Temples Preservation Law incorporated these debates
and codified architectural preservation as a modern
national practice.

“So, Can You Revit?” Historic Preservation Design Education and Digital Media
The impact of computer graphics and digital media on
architectural design cannot be overstated. In the last
fifteen years, design and construction in architecture
and engineering have completely changed due to
significant advances in technology. Today’s students
no longer use pencils, templates, vellum, or even the
antiquated AutoCAD. Rather, they practice integrated
design and Building Information Modeling (BIM),
an emerging design methodology that is radically
changing architectural practice. It will also change
architectural education, creating the need to integrate
construction technology and design. This is truly
the case when historic preservation is integrated
into architectural design education, where accurate
documentation and depiction of existing historic
resources is essential. As students race to implement
new design ideas within a historic resource—whether
it is an adaptive use project, rehabilitation, or
restoration—do they and can they understand how the
resource is constructed? Is there an understanding of
what is “real” and what is virtual? Teaching historic
preservation using integrated design and BIM creates
both challenges and opportunities in the design
studio.

“So, Can You Revit?” Historic Preservation Design Education and Digital Media
PAUL HARDIN KAPP
Every spring at architectural schools, career fairs
or “expos” draw architectural firms from across
the country to set up booths to distribute literature
and employment applications. Students, professionally
dressed and with portfolio in hand, seek the promise of
a job after a graduation. Employers ask students about
their knowledge of building and architecture; they may
even be interested in learning about ideas students are
developing in their theses. But, according to graduate
students in architecture, it appears that they are looking
for graduates who are proficient in the latest digital
media and can produce renderings using the latest
technology in Building Information Modeling or BIM. It
is during this professional courtship that the inevitable
question is asked: “So, can you Revit?” “Yes, I do,”
replies the twenty-first century architectural student.
The December 2008 McGraw Hill Construction
Smart Market Report, entitled Building Information
Modeling, notes that 43 percent of American Institute
of Architects (AIA) member architectural firms now
use BIM software. Revit, a three-dimensional building
design software platform made by Autodesk, is
one of many digital media being used for BIM. It is
anticipated that BIM use in the architecture profession
will increase dramatically; experts in BIM predict that
by the end of 2009, 54 percent of AIA member firms will
be using it to design buildings. BIM has been widely
accepted by the architectural profession, and the AIA
is promoting it outright. As noted BIM expert Harvey
Bernstein states: “Your career and the prosperity of
your company depend on becoming familiar with
the tools, processes and value propositions of BIM”
(Young, Jones, and Bernstein 2008). During this period
of change, architectural firms face an immediate and
difficult choice: outsource BIM work or hire staff familiar
with the new technology. Today’s architecture students
who have grown up with computer technology, have
embraced digital design media and are now ready to
help the design profession implement BIM. But the
question remains: Do they have the basic architectural
education foundation needed to design buildings that
will actually be built?
BIM is not just a new computer-generated graphic
tool; it is the database facet of an entirely new way
of designing and building called integrated practice.
Integrated practice is the construction industry’s
response to the marketplace mandate for buildings
that can be completed faster, cost less to design
and construct, and are more sustainable. Integrated
practice is collaborative; it relies on a free exchange of
information among all parties involved in the building
process. This includes not only design professionals
and contractors but also cost estimators and vendors,
code officials, and outside reviewers (e.g., review
architects in a SHPO). But BIM does not stop at the
completion of the project; it can be used to manage
the building after occupancy. Today, more and more
facilities managers are benefitting from BIM. They
envision facilitating building lifecycle management,
even from remote locations. BIM has the potiental to
transform the construction industry, and it is beginning
to be embraced as a teaching tool in academic
architectural design studios (Reams 2009).
In most architectural schools, basic computer
graphics such as AutoCAD are introduced early
in undergraduate studios and laboratories. Since
graphics is rarely the focus of advanced architectural
design studios, today’s computer-savvy students learn
the latest computer graphics, such as Revit, either in
other classes, in studios, or outside the classroom.

Students are attracted to Revit as the preferred product
for BIM for its dimensional graphic abilities, as well as
for its accessibility in schools.
BIM is much more than the latest computer
drafting package; it is the departure point into a
completely new realm of architectural design, practice,
and documentation. The basic concept of BIM is to
develop a “virtual building model” that will guide its
own building process; as the physical building is
assembled, changes in the field are documented in
the virtual model. As the actual building is completed,
the virtual building is used to document operations and
maintenance (paper documentation may even vanish).
Distinct phases of design will be merged, and the
process of both design and construction will become
fluid, blurring the traditional distinction between
architect and contractor.
Design professions have struggled to adopt and
implement BIM; only recently has the AIA addressed
this new trend in a series of papers to its board and
membership (Walbridge 2007). Although the premise
of BIM was conceptualized by Charles Eastman at
Georgia Tech in the 1970s, the term was coined by
software vendor Autodesk in 2002. Like Computer
Aided Design (CAD1), developed in the 1970s, BIM’s
development stems from mass manufacturing, not
from architecture. Its strength lies in its immediate
integration of design and fabrication and its abilty to
describe architectural design in three dimensions. Its
3-D capabilities made it attractive early in the 1990s
to abstract Modernist architects such as Frank Gehry,
who relied on BIM to piece together his audacious
designs, such as the Guggenhiem Museum in Bilbao,
Spain, and the Experience Music Project in Seattle,
Washington. Initially, Gehry and his firm used a BIM
software developed in France called CATIA. After
several years of adapting and revising the software
in their office, Gehry Partners started their own BIM
software company, Gehry Technologies--which is now
a leader in BIM technology. Gehry is considered a
leading practitioner and innovator in BIM; he believes
that BIM’s greatest attribute is its abilty to accelerate the
design and construction process through immediate
design and construction integration and its ability to
facilitiate collaboration (Hill 2006). Designers are linked
to the BIM design and to a wide range of diverse “design
team” members, such as cost estimators, marketing
professionals, product vendors, and others. This allows
manufacturing to remain flexible; efficiency is improved
with the merging roles of designer and fabricator. But
in the construction professions, the blurred divisions
of services for building delivery become problematic.
Who is truly responsible for the design, and who is
responsible for execution and construction? Where
do vendors fit into the design building process?
Finally, whose design is it when everyone has a role
in the process? Are students in traditional architectural
schools being taught to be team members for this bold
new world?
The possibilities of BIM are limited only by the
power of designers’ imaginations and the limitations
of computer software; designers are not restrained
by the normal conventions of graphic depiction (plan,
section, elevation) in architecture. Instead, they have
the ability to build and manipulate a three-dimensional
model in the actual specifications of the building
(albeit on the computer screen) and can import details
from vendors. Designers can link their models to the
International Building Code. Code analysis can occur
instantaneously, while heating and cooling loads are
readily calculated. Engineers can work simultaneously
with architects to design a building, while estimators
can readily determine if the design is financially feasible.
Another benefit? This can all be done remotely.
So, how can BIM work within the context of a historic
resource? After all, historic resources are existing
buildings; they were not developed in a virtual world, and
their conditions and parameters are real. Moreover, no
two historic resources are exactly the same. The passage
of time allows buildings to evolve; unfortunately, changes
in time are not documented graphically until a design
project makes it necessary to do so. What are typically
preserved are often unique architectural components
that were crafted exclusively for the historic building or
artifact. How are these buildings documented within
the framework of BIM? This question is fundamental
for those of us who teach historic preservation and
architectural design. There is an urgent need to better
integrate historic building technology, materiality, and
construction practice in the design studio using BIM.

Those who studied architecture and designed by hand
on drafting tables can easily become Luddites in the
face of the new generation of architects and the powerful
digital tools that allow them to produce an astonishing
amount of work. Most historic preservationists are
attracted to historic buildings because of their love of
handmade craft. Students of the last century enjoyed
the art of drafting and were enamored of architects of an
earlier time who eloquently depicted designs on linen
sheets using ink pens. Old copies of trade magazines
such as Pencil Points were references. Although some
architecture schools, such as Notre Dame, have made
these traditional graphic depictions a primary aspect
of their program, it is unrealistic to believe that today’s
design professional can avoid digital technology.
As a whole, the academy has been slow in
implementing digital design in the architectural studio.
Initially, this delay was due to the high cost of computer
technology for cash-strapped schools. Twenty years
ago, it was generally expected that universities could
provide computer laboratory space for students through
student fees and tuition. Computers in the architecture
studio were bulky, and CAD software was expensive,
slow, and prone to crashing (University of Illinois at
Urbana-Champaign 2002). However, the advent of the
laptop and the rapid development of graphic software
have changed everything. Now it is commonplace for
students to create their designs on their own laptop
computers while in studio. In addition, wireless internet
allows students immediate access to information,
including technical data that had previously required
hours of research in the library. Finally, architecture
schools no longer look at computer labs as overhead.
Instead, computer printing laboratories have become
lucrative business ventures supported by user fees.

stuDio
In a historic preservation studio at the School
of Architecture at the University of Illinois at
Urbana-Champaign during the 2008 fall semester,
students explored the application of BIM in historic
preservation design. The studio comprised fourteen
first-year graduate students, all of whom had
undergraduate degrees in architecture and were
pursuing a Master of Architecture degree. Half of
the students had declared historic preservation as
their study option, and all of them had a working
knowledge of BIM, using Revit as a computer
platform. The design assignment was two-pronged:
the expansion of the Carolina Inn and the adaptive
use and rehabilitation of Whitehead Residence
Hall, both on the campus of the University of North
Carolina at Chapel Hill.
The Carolina Inn is a historic luxury hotel (Figs. 1,
2) that serves the University and the Town of Chapel
Hill; Whitehead Residence Hall (Fig. 3) is a dormitory
located directly to the south of the inn. These
two buildings are listed on the National Register
of Historic Places, both share common stylistic
traits (early twentieth-century Collegiate Colonial
Revival), and both are contributing resources to a
national and local historic district in Chapel Hill. The
challenge was to make Whitehead Hall part of the
hotel complex. Students were asked to reprogram
Whitehead for luxury suites and new hotel rooms and
to add new services to the inn, such as a swimming
pool and a new dining facility. Finally, students
were asked to address a significant grade change
between the two buildings, involving infrastructure
and the preservation of sizeable trees. A main
aspect of the problem was to understand and use
“as-built” (building documentation based solely on
the construction of the design of a building) and “as
designed” (construction drawings and specifications
used for bidding and construction that do not
document any changes made in the field) (Figs. 4,
5).2 Students had full access to original construction
documents and all site, infrastructure, and UNC
Facilities Services documentation.
Students chose Revit, one of the more popular
BIM software,3 to develop virtual models of the
Carolina Inn and Whitehead Hall. Because they
were unable to make onsite measurements, the
model developed in Revit was based solely on the
documentation they were able to obtain. Students

analyzed the architectural and historical significance
of the two buildings and the overall context of the site
within the historic district; they developed a program,
a zoning analysis, and a building-code analysis. The
most frustrating aspect of the assignment was the
time consumed in accurately depicting the Carolina
Inn and Whitehead Hall in detail. The students were
quite skillful in using the graphics provided by Revit.
But they quickly learned that Revit requires its users
to accurately design every feature of a building at
a bid and construction-ready level. In a white paper
written for Autodesk, Professor Lachmi Khemlani of
the University of California at Berkley explains how
Revit software and BIM differ from both traditional
design practices and three-dimensional computer
graphic applications:

Preservation Education & Research Volume Two, 2009 19
Revit requires more communication and more
collaboration than working with AutoCAD, which
some people resist. Revit is a ‘designer’s tool,’ it
is more tactile and requires as well as facilitates
a complete understanding of the project both
at the micro and the macro levels. In current
practice, several people working at only the
micro levels feel threatened by the application’s
demand for a broader understanding of the
project. Revit also is anathema to those who
are not used to rigor in design. With Revit, you
cannot cheat or fake the form of a design, and
you cannot get away with missing information.
All parts of the building are required to co-relate
with each other. Folks who use traditional 3D
modeling applications often create images that
don’t coordinate with the project at all, and such
folks end up resisting the rigor and honesty that
Revit imposes (Khemlani 2004, 9).
Students learned that missing information had to be
confronted in order for the model to work. What could not
be learned from the existing documentation would have
to be verified in the field, which was impossible since
the project was near the East Coast. Students requested
information from the owner (UNC), the town planning and
inspections departments, and from the UNC archives,
architects, and engineers who had previously worked on
either the Carolina Inn or Whitehead Hall. What could
not be gathered through research would have to be
determined by an understanding of basic construction
technology and materials use. This immediately exposed
their true lack of understanding of how historic buildings
are built and raised the issue of how in-depth the design
problem should actually be.
As noted by Dr. Khemlani, the need for collaboration
with other design team members was realized using
BIM in the historic preservation design studio. Students
were required to thoroughly study and understand the
documentation, then use it to build a virtual model
in Revit. In order to facilitate the process, several
students built the virtual model while others built site
models. The need for model calibration challenged the
students to work in design teams. This opportunity for
collaboration is one of the most appealing aspects of
BIM; however, team building remains counterintuitive
in most design schools, which traditionally promote
individual creativity and competition. This is especially
true with first-year graduate architecture students.
The lack of material accurately describing the
Carolina Inn might not have been so problematic if the
project were handled at the traditional schematic design

level but, by using BIM, the level of design immediately
jumped to the level of construction documentation. The
issues of design level and model calibration imposed
impossible demands on first-year graduate students.
With BIM, calibration becomes the primary challenge
for a successful design both in the academic studio
and the professional office. It requires that the BIM
operator understand building technology. Calibration
also takes time and access to the existing building
(Cavallero 2006, 33).
During this project, two key opportunities were
missed by both students and faculty: the ability
to collaborate with others beyond the walls of the
architecture school and the ability to present and
critique solely in BIM. The students could have easily
engaged in online presentations with offsite experts.
Furthermore, by requiring students to present only
paper drawings of their design in plans, sections,
elevations, three dimensional-drawings, and models,
the faculty missed an opportunity to learn how BIM
can be taught.
Dr. Khemlani’s assertion of the honesty found in
Revit is somewhat misleading. Since Revit relies on
a library of building assembly details and graphic
representations of materials imbedded in the software,
the “honesty” she refers to is based only in the reality
that is found in Revit and not necessarily in the actual
artifact. This became problematic in documenting
the two historic buildings. For example, brick wall
surfaces in Revit were based on standard brick
sizes and American running bond patterns; both the
Carolina Inn and Whitehead Hall are built of oversized
brick in an English bond pattern. Moldings typically
found on early twentieth-century Colonial Revival
buildings were also not found in the Revit library and
could not be readily “pasted” into the model. Difficult
intersections and corner junctures typically found in
buildings with traditional moldings were non-existent
in the Revit software, which was conceived to design
modern buildings. In order to accurately depict the
existing conditions of the two buildings in Revit,
students had to research how traditional materials
were assembled, draw them orthographically in
AutoCAD, and import them into their virtual model.
Students also used technical reference books of the
period to gain an understanding of the way these
buildings were constructed (Fig. 6).
The use of Revit for a historic building using “as
designed” and “as built” documentation changed
the objective of the design problem; what originally
was intended to be an eight-week design of additions
and adaptive use had changed into a problem of
construction and materiality. Students were confronted
with how the role of structures, materials, and systems
impacted initial design decisions (Figs. 7, 8). Dr.
Khemlani acknowledges the problem of too many
design variables at the outset of the design process in
professional practice:

![Page 10: “So, Can You Revit?” Historic Preservation Design Education and ...](https://reader034.fdocuments.in/reader034/viewer/2022042800/58a032a31a28abea498c62ef/html5/thumbnails/10.jpg)
22 Preservation Education & Research Volume Two, 2009
Hand in hand with the ability of Revit to not
fake—a plus during the detailed design and
subsequent phases—also comes the inability
for abstraction, which all firms in the research
study found to be a negative during schematic
design. As discussed in the last section, Revit
requires complete modeling 100% of the time.
This requirement does not match the needs
of most architectural design processes at the
preliminary design stage. It does not support the
design flow, and is too restrictive and thereby
off-putting to those who actually conceptualize
the designs. This made several firms question
whether Revit should be used by a design
principal at all, given that it is not particularly
`sketchy’ (Khemlani 2004, 9).
revitCity
Clearly, the internet is no longer just a user-friendly
system of corporate and informational websites; it
is consumer-driven, with users “building” their own
cars, chatting live with other users, or creating their
own blogs and web pages. It is not surprising that
Revit has its own blog—Revit City. Interestingly,
it was not created by Autodesk but rather by a
communications company called Pierce Media
in 2003. Pierce Media intended the blog to be a
community website allowing Revit users around the
world to share their ideas. At Revit City, Revit users
display their three-dimensional work, add and use
an ever-expanding library of building details, discuss
the future of Revit in architectural design, and share
“snazzy workarounds.”
Today’s architecture students gravitate to Revit
City. It is a reflection of their generation, it supports
the competitive nature of architecture students by
giving them a perceived edge over their peers, and it
allows them to impress design faculty and perspective
employers. What is surprising – and to some
disappointing—is the lack of discussion regarding
actual design and construction. For example, Revit
bloggers discuss the graphic representation of a virtual
storefront rather than how it is assembled in the field.
Part of this can be attributed to the fact that students
are not building in the field; they are designing in the
academic studio. Also, users who are professionals
simply need instruction on the latest architectural
software rather than advice on building. Furthermore,
the purpose of this software program is just that; it is
a computer design tool, not a building aid. Real world
applications have no place here.
However, the phenomenon of Revit City cannot be
overstated. Similar to Wikipedia, Revit City demonstrates
the fluidity of ideas found on the internet. Unfortunately,
not all information is factual or reliable. Rather than
consulting the numerous online technical briefs from
accredited organizations, such as the Brick Institute
of America (BIA), Sheet Metal and Air Conditioning
Contractors National Association Inc. (SMACNA),
and even the Secretary of Interior’s Standards and
Preservation Briefs, students often rely on Revit and
Revit City exclusively for design guidance. Apparently,
the attractiveness of graphics trumps the need for
technical understanding, especially when building a
historic building. An emphasis on researching historic
construction to make informed decisions should be
brought back into the academic design studio. Only a
grounded and integrated foundation of understanding
in construction and historic building technology can
address the problems that have been exposed while
using Rivet (Figs. 9, 10).
Another negative aspect of Revit (and other BIM
products) is, as mentioned, the lack of historic resource
graphics. When students could not find Colonial
Revival moldings or English bond brick patterns,
they simply created their own. Actually, not so simply.
Creating a virtual historic detail in Revit is laborious,
even more so than in other design software. If Revit is
to be used successfully in the academic studio, then
design problems need to be tailored for use with BIM
programs such as Revit.
It is interesting to note that at this moment in the
BIM revolution there is a generational divide in the
acceptance and use of digital media as a design
methodology. Design professionals are resistant
to change and are not comfortable discarding the
traditional track of project delivery: schematic design,
design development, construction documentation,

bidding and construction—even though all of the
professional design associations are embracing this
new technology.4 Other design professionals (especially
the new generation) embrace this technology and are
motivated to produce impressive graphics. While the
next generation of architects may be able to say, “Yes,
I can Revit,” will they be able to say the same for the
more important question, “Do you understand how
to design? How to build?” And, more importantly,“Do
you understand the fundamental ideas of historic
preservation?”
theFuture
At what point should all facets of building technology—
historic building construction, structural integration,
environmental system integration, and Building
Information Modeling (BIM)—be integrated into the
design curriculum? Early and succinctly in the education
of an architect. The market demands it. As the design
and construction industries continue to transform into
the new fluid model called integrated practice (using
BIM), today’s architecture and historic preservation

students will be thrust into the forefront of the revolution.
But the market is not just demanding “BIM operators”; it
is demanding competent designers on the cusp of being
licensed professionals in architecture or engineering.
Never has a design tool demanded so much knowledge
from its users. In order to truly master BIM, one must
have a sound understanding of all facets of materials,
construction practices, and the mechanical, electrical,
and plumbing systems found in buildings. The ability to
make such an immediate leap from sketch to building
changes the entire dynamic of the architectural design
process from a question-driven method to an answer-
driven one (Cheng 2006) This paradigm shift in thinking
runs against the way architecture has always been
taught— as a process of discovery—in the academy.
The challenge of using BIM in a historic preservation
design studio is even more problematic. Calibration
between the existing building and the computer model
immediately becomes an important issue. Students will
need to adjust their expectations of finding all they need
either in software-provided detail libraries or by visiting
sites such as Revit City; they will have to continue the “old”
practice of searching for archival documents, drawings,
and images. Instructors in historic preservation will have
to challenge their students to see past the impressive,
often misleading graphics. The objective is not to teach
a new graphic design tool (which will surely change) but
to teach critical thinking in both architectural design and
historic preservation, never substituting “why” with “how
to” (Cheng 2006).
Physical historic resources should not be forgotten
when designing in a “virtual” world. In a July 1972 article
in the National Trust’s monthly newspaper, Preservation
News, Bob Stipe stated it best:
First we seek to preserve our heritage because
our historic resources are all that physically link us
to our past. Some portion of that patrimony must
be preserved if we are to recognize who we are,
how we became so, and, most importantly, how
we differ from others of our species. Archives,
photographs and books are not sufficient to
impart the warmth and life of a physical heritage.
The shadow simply does not capture the essence
of the object (Stipe 2003, 13).
One should add “computer-produced virtual
model” to Stipe’s list. The relationship of physical
object and designer is vital to successful design in
historic preservation, whether it is a rehabilitation,
restoration, or an adaptive use project.
As technology accelerates the design process,
it should not accelerate our methods for teaching
preservation. Although it can be argued that the
concept of integrated practice is both real and
attainable, one cannot make the same conclusion
about an integrated practice curriculum, which, at
this point, has proven to be unrealistically demanding
on students (Cheng 2006). Preservation instructors
should continue to emphasize how historic buildings
work and help students develop the analytical skills
needed to preserve them. Important issues of design
and preservation, such as architectural integrity,
should not be jettisoned to allow students time to
develop impressive graphics of designs that they may
not even understand.
One must also not lose sight that BIM/Integrated
Practice will provide numerous professional
opportunities for future generations of preservationists.
As a tool for design collaboration, BIM allows
preservationists to access the design process early
and often; this can provide great benefits in preserving
the integrity of historic resources in the design
and construction process. As a product of a global
economy, BIM/Integrated Practice allows both the
student and the professional to collaborate more, not
only outside the studio walls but with other students
and professionals across the planet.
The possibilities of an integrated practice and
opportunities for collaboration are more difficult to
simulate in the academic studio. The ability to accelerate
the design process, the primary pitch for using BIM by
its proponents, may not be such an attractive attribute
for teaching students design and preservation. “Real
world” situations using BIM may not be the best way to
use this design tool when teaching design with historic
resources. This may especially be the case as students
learn the importance of building documentation in
the preservation process. Calibration between what
is real and what is virtual will continue to become an
important aspect of teaching historic preservation

using BIM. Unlike new building design in which a
relationship exists between virtual model/design and
the construction/physical manifestation of the building,
historic preservation design adds an entirely new level
to the design process—that of existing conditions; the
chain of calibration in preservation should be: existing
building, virtual model, and construction. The need for
rigorous building investigation and verification, which
is often time consuming, is extremely important. BIM
does not provide shortcuts in the process; it simply
states the deficiency of information.
BIM requires a high level of expertise in designing
with historic resources. Only through fundamental
learning, understanding the potential of BIM in historic
preservation projects, and years of experience can
that expertise be attained (the latter conclusion applies
to any media in design). In using BIM as tool in the
academic studio, one must respect its capabilities but
also be mindful of its limitations; BIM is answer-driven
not question-driven. Helping students develop their
analytical skills and judgment in historic preservation
lies at the core of historic preservation education. BIM
should be used only as an analytical tool, alongside
sketching, drafting, and hand measuring, enabling the
architecture student to understand the process rather
than allowing “the machine” to do the work.

Paul Hardin Kapp is an associate professor of architecture and
director of the historic preservation option at the University of
Illinois at Urbana-Champaign School of Architecture. He previously
served as the Campus Historic Preservation Manager and Historical
Architect at the University of North Carolina at Chapel Hill, where
he designed or managed more than a dozen historic rehabilitations
of campus landmark buildings. He was also a lecturer in historic
preservation and American vernacular architecture in the UNC
Department of City and Regional Planning. At Carolina, Mr. Kapp
managed over $150 million of capital-construction funds. Kapp’s
work was recognized by Preservation North Carolina and won
awards from the Preservation Society of Chapel Hill. In 2007, he
received a Getty Campus Historic Preservation Grant to develop
a historic preservation landscape master plan for the Carolina
campus. Prior to coming to Carolina, Mr. Kapp had a successful
private practice in rural Virginia. Several of his historic rehabilitations
earned preservation awards from the Preservation Alliance of
Virginia and the Association of General Contractors of Tennessee.
Mr. Kapp is a registered architect (Virginia, West Virginia, North
Carolina, NCARB) and a LEED Accredited Professional, with more
than twenty years of experience in historic preservation.

Computer Aided Design products include Autodesk, ArchiCad, and Bentley Systems. Students had access to “as designed” drawings and specifications of the original 1924 Carolina Inn by Arthur Nash, Architect; the 1971 addition to the inn by Archie Royal Davis; and the 1991 addition to Inn by Glave, Newman and Anderson Architects. Students also had access to “as built” documentation compiled by the UNC Engineering Information Office. Several companies produce BIM software, such as Rhinoceros, Bentley, Graphisoft, and ArchiCad.In an article entitled “The Bim Revolution,“ architect H. Michael Hill (2006) writes “CAD drawings are very useful, and they clearly have contributed a great deal in terms of efficiency, process, and scope. Yet when you get right down to it, they represent little more than electronic applications of the age-old pencil-and-paper system that architects, specifiers, engineers, and others have been using for centuries.” He supports noted architect Frank Gehry, who makes the assertion that BIM provides the opportunity for collaboration and that it also introduces the fourth dimension—time—to the design process.
